Debris and Drainage Conditions That Affect Runoff
Every home experiences a different rate of debris buildup depending on surrounding conditions and building design. Common factors that influence roof drainage include:
- Leaves, twigs, seed pods, and pine needles settling inside open channels.
- Windblown dust, roof shingle grit, and decaying plant matter forming dense silt.
- Downspout strainers or elbows becoming obstructed by compacted material.
- Standing water that remains trapped due to improper channel slope or partial clogs.
